processing the table."
::= { flowRuleEntry 2 }
flowRuleSelector OBJECT-TYPE
SYNTAX RuleAttributeNumber
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"Indicates the attribute to be matched.
null(0) is a special case; null rules always succeed.
v1(51), v2(52), v3(53), v4(54) and v5(55) select meter
variables, each of which can hold the name (i.e. selector
value) of an address attribute. When one of these is used
as a selector, its value specifies the attribute to be
tested. Variable values are set by an Assign action."
::= { flowRuleEntry 3 }
flowRuleMask OBJECT-TYPE
SYNTAX RuleAddress
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The initial mask used to compute the desired value. If the
mask is zero the rule's test will always succeed."
::= { flowRuleEntry 4 }
flowRuleMatchedValue OBJECT-TYPE
SYNTAX RuleAddress
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The resulting value to be matched for equality.
Specifically, if the attribute chosen by the flowRuleSelector
logically ANDed with the mask specified by the flowRuleMask
equals the value specified in the flowRuleMatchedValue, then
continue processing the table entry based on the action
specified by the flowRuleAction entry. Otherwise, proceed to
the next entry in the rule table."
::= { flowRuleEntry 5 }
flowRuleAction OBJECT-TYPE
SYNTAX ActionNumber
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The action to be taken if this rule's test succeeds, or if
the meter's 'test' flag is off. Actions are opcodes for the
meter's Packet Matching Engine; details are given in the
'Traffic Flow Measurement: Architecture' document [9]."
::= { flowRuleEntry 6 }
flowRuleParameter OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create

DESCRIPTION

"The flow table group defines objects which provide the
structure for the rule table, including the creation time
and activity time indexes into it. In addition it defines
objects which provide a base set of flow attributes for the
adjacent, peer and transport layers, together with a flow's
